Current modulation in graphene p-n junctions with external fields
F. R. V. Araújo, D. R. da Costa, A. C. S. Nascimento +1
In this work we describe a proposal for a graphene-based nanostructure that modulates electric current even in the absence of a gap in the band structure. The device consists of a…
Excitonic gaps and exciton binding energies in multilayer phosphorene quantum dots
M. A. Lino, J. S. de Sousa, D. R. da Costa +3
Dielectric screening is greatly important to an accurate calculation of the exciton binding energies in two-dimensional materials. In this work, we calculate the dielectric functio…
Snake states in graphene quantum dots in the presence of a p-n junction
M. Zarenia, J. M. Pereira, F. M. Peeters +1
We investigate the magnetic interface states of graphene quantum dots that contain p-n junctions. Within a tight-binding approach, we consider rectangular quantum dots in the prese…
